Word 2010: Multiline Userform in VBA not working

Hi -- I'm really hoping someone can help me. I have a letterhead macro that I created for our office back in Word 97, and its worked fine all this time except now that we are upgrading to Word 2010, it is caving on a "makeonepar" code.

strAttn = MakeOnePar(txtAttn)

I have a multiline textbox for the user to enter more than one attention person and more than one line on the RE line while maintaining the hanging indent, so it was basically using a soft return. There isn't always more than one attention person or more than one line on the re line.
